Crawl Space Encapsulation & Repair

As a homeowner in Charleston, you know that the area is no stranger to humidity and rain, but you may not realize how these common occurrences affect your crawl space. Most crawl spaces use wooden beams to support the floors of your home. When excess moisture infiltrates your crawl space, it can cause these beams to experience wood rot or mold – putting your entire home at risk. Additionally, moisture in your crawl space can lead to increased energy bills, damaged insulation, and pests.  

Despite these many problem signs, Mount Valley Foundation Services has the tools and expert knowledge to keep water out of your Charleston crawl space. Crawl space repair and encapsulation involves the installation of a dehumidifier, vapor barrier, support beams, sump pump, vent covers, and more to completely waterproof your crawl space. We’ve been helping homeowners in North Carolina and South Carolina keep their crawl spaces dry since 1986, and we’re ready to help you too!

Crawl Space Problem Signs in Charleston

As mentioned, excess moisture in your crawl space leads to many problem signs below your home, especially during the rainy and humid summers in Charleston. Wood rot and mold can form on wooden beams which causes them to break down over time. As the wooden beams break down, your home may suffer from sagging floors. Mold spores may spread into your home, causing potential health problems and more mold growth. High moisture can also lead to increased energy bills as humidity travels from your crawl space and into your living area. Furthermore, the Charleston humidity attracts all kinds of pests – from insects to rodents.

Causes of Crawl Space Damage in Charleston

Obviously, moisture is the main cause of crawl space damage in Charleston, but how exactly does so much water get below your home? First, open crawl space vents allow humid air to easily penetrate the crawl space. Ineffective vapor barriers might also cause more damage if installed improperly. Another issue is over spanned floor joists that occasionally occur during construction. Essentially, these are beams that are built too far apart and are unable to support the weight of your home. Understanding these causes is the first step in repairing them!

Crawl Space Solutions

Crawl space repair and encapsulation keeps your crawl space dry and supported with many different tools. When used in tandem, these solutions offer the most efficient defense against excess moisture that any foundation company can offer. Keep moisture out with a vapor barrier and dehumidifier. After a heavy summer storm, move groundwater away from your crawl space with our internal drainage system and sump pumps. Keep your floor joists supported with our steel crawl space support beams. The best part is – all of our solutions are designed to provide a permanent fix for your crawl space!

Today we met Dickie Walters, field inspector, for mount valley foundation. He was everything you would want in a consultation about something as nerve racking as foundation issues. He was personable to the point where it felt comfortable, yet professional enough still to trust what he was saying. He spent a great deal of time walking through each room, assessing the house, and answering all of my questions, which were a lot!! I feel very confident about there products and services because of how Dickie conducted himself . I look forward to working with them. Feeling grateful !

We had Travis inspect our foundation. We suspected there were foundation issues. Another company inspected and quoted us 25k.

The consultation and the work performed was amazing.Cory Hawkins, Oscar Mota, and Brandon Waters explained the entire process and kept me updated throughout the 3 day job. The only reason for a 4 star is due to the scheduling process, as it was horrific to say the least. Permitting not completed and job scheduled and then job rescheduled more few times. Outside of that, the team was very professional and did a great job cleaning up.

Absolutely love this company. From start to finish the sales rep and the people on the job were attentive to all of our needs. Originally we were meant to have our job done next week but they had an earlier slot and asked if we wanted it.We said yes and they sent two teams out to work on it. They were kind and efficient. Even after ripping up all the old plastic down there they cleaned every piece up and left no trace behind. We love our new crawl space door and the dehumidifier is quite.Within two day we could already see a difference in the humidity under the house.They let us know of a leak we had which i appreciate greatly.I recommend them to any and everyone. Best company we have found by far.

William, Greg and Lewis worked on our house for 2 days. They installed 7 push piers the 1st day and 9 IntelliJacks the 2nd day. They did an excellent job with the installations. They back-filledthe holes, mortared the cracks and restored the landscaping so that it was almost impossible to tell any work was done. They were all very courteous, polite, professional and knowledgeable. I would highly recommend them. I would have given 5 stars, but one minor problem occurred. A light fixture was broken in the crawl space which I was not told about and discovered it after they left. I reported it to the company and a supervisor offered to come out to replace it, but I had already gotten replacement parts for it. It would have been nice if they offered a credit to my account instead. I wish I could give them 4 and 1/2 stars, but I'm limited to 4.
